This study reports mesostigmatid mites (Acari: Mesostigmata) collected from fresh bat guano in the aphotic zone of a natural cave in T & uuml;rkiye. Three species were identified, each belonging to a different family: Eulaelaps stabularis (Haemogamasidae), Macrocheles foliatus & Ouml;zbek sp. nov. (Macrochelidae) and Vulgarogamasus oudemansi (Parasitidae). Macrocheles foliatus & Ouml;zbek sp. nov. is described here as a new species based on morphological features observed in adult females. Vulgarogamasus oudemansi is recorded from T & uuml;rkiye for the first time. Two females of Eulaelaps stabularis were found directly in bat guano, and the presence of developing larvae suggests larviparity or ovolarviparity in this species. These findings expand current knowledge of cave-associated mesostigmatid diversity and provide additional information on the ecological role of bat guano habitats in supporting diverse mite assemblages in cave ecosystem.https://zoobank.org/urn:lsid:zoobank.org:pub:745CF591-023A-48F3-A4E9-824BB6923106

A new species, Camerotrombidium akınleventi sp. nov. is described based on both active postlarval forms and larvae. This is the third species of Camerotrombidium for which larval stage has been observed under laboratory conditions. Additionally, based on published records and original data, a checklist of trombidioid mites from Türkiye is compiled. https://zoobank.org/References/0448531d-dc2a-4c36-a974-41ac76de44f7.

Sphairothrombium gabrysisp. nov. is described based on the adult and larva. Larvae were obtained by laboratory rearing from a field-collected female. The larval stage of the genus is described for the first time. Sphairothrombium gabrysisp. nov. is the first species to be included in this genus since 1999, bringing the overall number of species assigned to this genus to 14. http://www.zoobank.org/urn:lsid:zoobank.org:pub:4022C01F-98E2-4E65-9515-E3000FDE0232.

This paper reports the presence of a malformation in an adult female specimen of Storchia robusta (Berlese) collected from Sansa Gorge, Turkey. In the species, local anomalies such as the number of aggenital, genital, and body setae have been previously reported; however, this is the first time atrophy in S. robusta has been recorded.

The present study was carried out to determine the incidence and density of Demodex folliculorum (Simon, 1842) and Demodex brevis Akbulutova, 1963 in patients with acne. The study included 210 patients diagnosed with acne during clinical examination, and 150 healthy controls without any facial dermatoses. In the study, samples were taken from the right cheek, left cheek, nasolabial area, and chin of the participants using the Standard Superficial Skin Biopsy technique. Samples were examined under a light microscope, and Demodex species were identified and counted. Demodex positivity (≥5 mites) was detected in 62.4% of the patients and 16.7% of the controls in the study (p < 0.001). A total of 3325 (mean: 25.4/cm 2 ) mites were isolated from Demodex-positive patients. A total of 2015 (mean: 19.2/cm 2 ) mites were isolated from patients infested with D. folliculorum only, 52 (mean: 7.4/cm 2 ) mites were isolated from patients infested with D. brevis only, and 1058 (mean: 65.2/cm 2 ) mites were isolated from patients infested with both species. The mean density of both mites (co-infection D. folliculorum and D. brevis) was detected as 21.0, 43.5, and 117.1/cm 2 respectively, in patients with mild, moderate, and severe acne. In the controls who was Demodex positive, only D. folliculorum or co-infection with both mites were detected, not D. brevis alone. A total of 167 (mean: 6.7/cm 2 ) mites were isolated from these controls. As a result, Demodex mites were found to be very common and intense in patients with acne in Erzincan, Turkey. It was also concluded that there was a positive correlation between Demodex mites and degree of acne, and that the co-infection of D. folliculorum and D. brevis aggravated the clinical picture in patients with acne. It may be helpful to consider these findings in clinical assessments of patients with acne.

A new species of the family Stigmaeidae, namely Stigmaeus indivisussp. nov., ex soil and litter under a creeper plant, is described and illustrated from Erzincan, Turkey. http://www.zoobank.org/urn:lsid:zoobank.org:pub:272FD9F9-436F-4CAC-BE2F-7F276D716E5F.

Pachydellus giresunensissp. nov. was collected from Pinus litter in Giresun Province, Turkey. It is a member of the Pachydellus sculptus species group. The new species differs from other species in the group by its very long dorsal shield setae and the absence of tubercles on femur IV of the male. The fauna of Pachylaelapidae found in Turkey is reviewed, and some new records are added. http://www.zoobank.org/urn:lsid:zoobank.org:pub:E0629819-82EB-46EF-B8A2-005A445E2F4E.

Pachyseius accedenssp. nov. and Pachyseius arrhenobasissp. nov. are described and illustrated based on specimens from litter and soil detritus of montane forest habitats in Bulgaria (Rhodope Mts., Malesh Mts.) and Romania (Carpathian Mts.: Bârgău Mts., Călimani Mts.), respectively. In addition, Pachyseius angustiventris Willmann, 1935, a little known and inadequately described congeneric species, is newly redescribed and illustrated, based on females from the Western and Central Europe (Wales, Germany). Comparing the type material of the following species, Pachyseius morenoi Moraza, 1993 is not considered to be a valid species, and is included in synonymy with P. angustiventris.

Pachylaelaps (Longipachylaelaps) anatolicus sp. nov. is described based on the females collected from litter in north-eastern Turkey. The new species may be distinguished from the other congeners primarily by the multidentate chelicerae and spiniform epistome. The subgenus Longipachylaelaps is first reported from Turkey.

Nothrholaspis bilobatus sp. nov. is described based on females and males collected from litter and moss in north-eastern Turkey. The new species shows a previously unknown form of sexual dimorphism, with a pair of sclerotized lobes in the anal region of the male. A new key to females of all known species of the genus is provided.
